In view of this, be in fact necessary to provide one to enter gluing mechanism, this enter gluing mechanism can solve exist in above-mentioned technology can leave problem into glue trace in appearance at it when injection molding product.
[summary of the invention]
Therefore, the object of the present invention is to provide one to enter gluing mechanism, this enters gluing mechanism and can solve and above-mentionedly can leave problem into glue trace in appearance at it when injection molding product.
In order to achieve the above object, of the present invention enter gluing mechanism, it is applied in mould, the male template that this mould comprises a mother module core, a male die core, is provided with hot runner and once liftout plate, and this enters gluing mechanism and comprises:
One runner, it to be located in described male die core and to be communicated with described hot runner, to enter the direction of glue for vertical direction, this runner comprises the first vertical section, horizontal segment and the second vertical section from top to bottom successively on the direction entering glue, the two ends of described horizontal segment section vertical with described first and second vertical section is vertical is connected respectively;
One taper pin, this taper pin one end is located in described male die core, and the other end is placed in described male template, and this end that taper pin is placed in male template is provided with a sliding tray; And
One ejects part, and this ejects part one end and is located on described lower liftout plate, and the other end is placed in described sliding tray.
Preferably, described runner is communicated with hot runner by the first vertical section.
Preferably, described taper pin is located at this end in male die core and horizontal segment and second vertical section is corresponding contacts.
Preferably, be provided with an avoiding hollow groove in described male template, this end that taper pin is located in male template is placed in this avoiding hollow groove.
Compared to prior art, of the present invention enter gluing mechanism, by arranging multistage buffering structure runner in male die core, to make the plastic cement entering runner after the multistage buffering through runner, injection pressure is released gradually and disperses and be injected in die cavity in the mode of gentleness, so after formed product, can not leave in appearance into glue trace at it.
[accompanying drawing explanation]
Fig. 1 illustrates the generalized section directly entering gluing mechanism of prior art.
Fig. 2 illustrate prior art common enter the generalized section of gluing mechanism.
Fig. 3 illustrates the generalized section that the present invention enters gluing mechanism.
Fig. 4 illustrates generalized section when the present invention enters the die sinking of gluing mechanism.
[detailed description of the invention]
Refer to shown in Fig. 3 and Fig. 4, wherein Fig. 3 is the generalized section that the present invention enters gluing mechanism, and Fig. 4 is the generalized section of the present invention when entering the die sinking of gluing mechanism.
Of the present invention enter gluing mechanism, it is applied in mould, and this mould comprises male template 103 and the once liftout plate 104 that mother module core 100, male die core 101, is provided with hot runner 102, and in the present embodiment, refer to Fig. 3, this enters gluing mechanism and comprises:
One runner 105, this runner 105 is located in described male die core 101, this runner 105 one end communicates with described hot runner 102, in the present embodiment, this runner 105 is step structure, to enter the direction of glue for vertical direction, this runner 105 comprises the first vertical section 1051, horizontal segment 1052 and the second vertical section 1053 from top to bottom successively on the direction entering glue, the two ends of described horizontal segment 1052 section vertical with described first 1051 and second vertical section 1053 is vertical is connected respectively;
One taper pin 107, this taper pin 107 one end is located in described male die core 101, and the other end is placed in described male template 103, and this end that taper pin 107 is placed in male template 103 is provided with a sliding tray; And
One ejects part 108, and this ejects part 108 one end and is located on described lower liftout plate 104, and the other end is placed in described sliding tray.
Wherein, described runner 105 is communicated with hot runner 102 by the first vertical section 1051.
Wherein, described taper pin 107 is located at this end in male die core 101 and horizontal segment 1052 and second vertical section 1053 is corresponding contacts.
Wherein, be provided with an avoiding hollow groove 106 in described male template 103, taper pin 107 this end be located in male template 103 is placed in this avoiding hollow groove 106, and when mould die sinking, this avoiding hollow groove 106 can provide abundant exercise space for taper pin 107.
In the present embodiment, refer to Fig. 3, when mould matched moulds, the plastic cement of melting is injected in runner 105 by hot runner 102, the flow process of plastic cement in runner 105 is: plastic cement is injected in the first vertical section 1051 through hot runner 102 at first, be injected in horizontal segment 1052 through the first vertical section 1051 again, then be injected in the second vertical section 1053 through horizontal segment 1052, injection pressure is released gradually and disperses after the multistage buffering through runner 105, last plastic cement is injected in die cavity in the mode of gentleness through the second vertical section 1053, stop when die cavity fills injecting plastic cement, product 13 is shaping to be completed.
In the present embodiment, refer to Fig. 4, when mould die sinking, to enter glue direction for vertical direction, lower liftout plate 104 moves upward, drive thimble 109 and eject part 108 and move upward simultaneously, sliding tray is placed in owing to ejecting part 108 one end, so eject part 108 can not depart from taper pin 107 in motion process, taper pin 107 moves obliquely upward after being subject to ejecting the active force of part 108, namely taper pin 107 simultaneously upwards and move right, taper pin 107 departs from type plastic cement in runner 105, in addition, the active force that product 13 is subject to thimble 109 is upwards ejected and is departed from male die core 101, because plastic cement in type in runner 105 and product 13 are connected as a single entity, so in type plastic cement and product 13 move upward in runner 105 simultaneously, take out product 13, mould matched moulds, start injection molding product 13 next time.
Compared to prior art, of the present invention enter gluing mechanism, by arranging multistage buffering structure runner 105 in male die core 101, to make the plastic cement entering runner 105 after the multistage buffering through runner 105, injection pressure is released gradually and disperses and be injected in die cavity in the mode of gentleness, so after product 13 is shaping, can not leave in appearance into glue trace at it.
